Blockchain technologies have created newer avenues of growth for various businesses, especially within industries prone to large-scale security risks. However, all technological advancements have their share of disadvantages, and blockchains are no exceptions.
It’s wise to weigh their pros and cons before you dive headfirst into them. In this article, I detail some of the benefits and drawbacks of blockchain technology. Keep reading to know more!
Advantages of Blockchain
Decentralization
Decentralization is a crucial feature of blockchain technology. Blockchain transactions are verified through mining, unlike traditional payment systems, where transactions are authenticated by an intermediary (such as a bank or a credit card company).
Blockchain systems thus eliminate the risk of relying on third-party organizations to authenticate a transaction. By cutting out intermediaries, they help reduce overall costs and intermediary fees.
Network Distributions
Storing blockchain data across thousands of devices on a distributed network of nodes ensures that no single person owns the network. There are no single points of failure across the web, which means that a single offline node cannot interfere with the security of the whole network.
With a distributed network, false and malicious information cannot exist because various participants must verify the data.
Lower Costs for Users
Once you create block data, it becomes incredibly challenging to reverse it. So data stored on a blockchain cannot be tampered with easily. This makes blockchain systems immensely appealing to businesses with high-security risks, such as financing firms.
It’s also a great way to maintain financial records as every transaction that occurs on a blockchain is permanently scrutinized and recorded on a public ledger.
Disadvantages of Blockchain
Inefficiency
Mining is a highly competitive process, and it is inefficient to have several network users verify duplicate transactions when only one of them reaps the benefit. Blockchains are also not very environment-friendly, as when miners try to increase their computational power to find a valid block hash, they consume a lot of energy.
Private Keys
Blockchains come with a public address that can be shared across the user network and a private key, which is meant to be kept secret by a particular user. You cannot access your blockchain data or funds without your private key.
It is impossible to recover a private key if it’s lost, meaning that the funds on your blockchain are effectively lost.
Storage
The larger the number of users, the larger the number of transactions integrated into a blockchain. When your ledger grows too large, it can exceed the capacity of mining hard disks.
This could pose a severe problem in the future because if your users cannot effectively download and store the blockchain data, your network could lose nodes.
Despite its drawbacks, blockchain technology has revolutionized the digital world. Various industries are trying to work their way around its shortcomings and effectively implement them in business avenues that will yield the most value. Keep yourself informed about the latest trends in blockchain technology before investing in it.
